founder of I.S.F.Malcolm Hamer, present owner

Many things have changed since then, except: (a)
I.S.F.'s determination to please its customers, and (b) I.S.F.'s
logo.

When established in 1932, ISF-UK had
offices in London and Blackpool, where Mr Goodhead also owned a number of retail
establishments. The present owner of I.S.F., Malcolm Hamer, was born in
the U.K. He studied Physics at Oxford University, and has worked for a
number of large multinational companies in Europe and Asia. He moved to New York in
1981.
